(5) SO1n output (see (a) in Figures 15-1 and 15-2)
The status of the SO1n output is as follows if bit 7 (CSIE1n) of serial operation mode register 1n (CSIM1n) is
cleared to 0.
Notes 1.
Caution If a value is written to TRMD1n, DAP1n, and DIR1n, the output value of SO1n

changes.
The actual output of the SO10/P12 or SO11/P74 pin is determined according to
PM12 and P12 or PM74 and P74, as well as the SO1n output.
